Lithospheric electrical conductivity structure across Southern Scotland and Northern England
Magnetotelluric soundings in the range (100-0.01Hz. ) have been carried out along a
140 km. profile across S.Scotland and N.England. Following discussion of the steps
taken to reduce cultural noise in the response functions, the results for 13 stations
along the traverse are presented. Since the study of dimensionality parameters
supports 1-D modelling, rotationally invariant resistivity-depth data have been
subjected to two 1-D inversion schemes and the different parameters of the model
derived have been examined using the Most squares approach. Two dimensional
numerical modelling has also been carried out considering both the present data and
those of earlier induction studies along the profile.The resulting geoelectrical model confirms the existence of a crustal conducting layer
(10-50 Ohm.m.) as found in earlier induction studies. Results of this study show
additionally that- a) the conductor rises to a depth of nearly 3.5 km. about 20km.
south of the SUF i.e., near the axis of the Eskdalemuir magnetic variation anomaly b)
the conductor is at a depth of about 8-10 km. in region of the Weardale granite in
N. England, c) there is a marked resistivity-depth variation below S.Scotland and d) the
surface resistivity along the profile decreases from NW to SE and corresponds well to
the Ordovician, the Silurian and the Carboniferous sediments. The geophysical
interpretation of the model has been discussed in association with the results of
earlier induction studies, seismic and gravity studies and the various tectonic models
of the Iapetus suture zone. Based on the present study and comparison with electric
structures of other tectonic regions, a hypothetical tectonic model has been proposed
for this study region. It comprises a resistive triangular wedge surrounded by a
conducting layer which is incorporated as a signature for the presence of a subducting
plate in an island arc environment.In addition to these field investigations, several computational analyses have also been
undertaken. The main studies were - a) procedures to reduce noise from the
recorded data using digital filtering techniques and b) determination of the
distortion of telluric field measurements due to a conducting hill using a conformal
mapping method. Digital filters have been discussed with special reference to
persistent noise signals, eg. power lines, electrical fences etc. Delay line filtering,
notch filtering and the maximum entropy method have been applied to both synthetic
and field data and the results are discussed. The effect of a two-dimensional
conducting hill on the telluric fields measured on a horizontal surface has been
studied using the Schwartz-Christoffel conformal transformation technique. The
results indicated that the distortion depends strongly on the inclination, height of the
hill and depth to the basement. The distortion of apparent resistivity values computed
from MT field measurements has also been discussed.In addition, some consideration has been given to - a) the processing of the data in
the time domain using adaptive filters, b) the application of joint inversion of DC-AMT
data to resolve shallow structures in N.England and c) the distortion effects of near
surface inhomogeneities in N.England.These various studies are presented in 7 chapters with 3 Appendices and the results
are discussed in chapter-8, where the conclusions and suggestions for further work
are also presented

The role of social tags in web resource discovery: an evaluation of user-generated keywords
Social tags are user generated metadata and play vital role in Information Retrieval (IR) of web resources. This study is an attempt to determine the similarities between social tags extracted from LibraryThing and Library of Congress Subject Headings (LCSH) for the titles chosen for study by adopting Cosine similarity method. The result shows that social tags and controlled vocabularies are not quite similar due to the free nature of social tags mostly assigned by users whereas controlled vocabularies are attributed by subject experts. In the context of information retrieval and text mining, the Cosine similarity is most commonly adopted method to evaluate the similarity of vectors as it provides an important measurement in terms of degree to know how similar two documents are likely to be in relation to their subject matter. The LibraryThing tags and LCSH are represented in vectors to measure Cosine similarity between them
Assessing the tagging behaviour of kannadigas: A study of hash tags in twitter
Tweeting is the fastest communication media now. It is short and simple. It is a microblogging service. Hashtags are the organizational component adopted by Twitter. Tweets is Kannada are available for some years now.But, Twitter opened up Kannada for hashtags in February 2015. The study focuses on the analysis of the 3158 Kannada tags collected from 1993 tweets. There is an increasing trend for using hashtags in Kannada. There are very lengthy tags as well
Wikipedia and LIS: A study of coverage of concepts for UGC-NET
UGC-NET is an eligibility examination for those who are aspiring for the academic jobs in the universities and colleges in India. There are multiple sources, mainly printed publications, available for preparation of UGC-NET exams. The present study examines the suitability of Wikipedia as a source for preparation. The 396 topics culled from the UGC-NET syllabus in LIS was compared for their coverage in Wikipedia. It was found that 55.55% of the topics are available on Wikipedia. The answers to the previous years’ questions were also searched. The study found that 35.48% of answers could be traced in Wikipedia. The Wikipedia was also examined from other parameters such as up-to-datedness, comprehensiveness, illustrations, and references and external links. The analyses show that Wikipedia could be a source for preparation for UGC-NET. The study has an implication for those who are seeking the eligibility for the jobs through UGC-NET
Interpreting Pursuit Outcomes from Data Web Bases
The Internet presents a huge amount of useful information which is usually formatted for its users, which makes it difficult to extract relevant data from various sources. Therefore, the availability of robust, flexible Information Extraction (IE) systems that transform the Web pages into program-friendly structures such as a relational database will become a great necessity .The motivation behind such systems lies in the emerging need for going beyond the concept of “human browsing.”The World Wide Web is today the main “all kind of information” repository and has been so far very successful in disseminating information to humans[5]. The Web has become the preferred medium for many database applications, such as e-commerce and digital libraries. These applications store information in huge databases that user’s access, query, and update through the Web. Database-driven Web sites have their own interfaces and access forms for creating HTML pages on the fly. Web database technologies define the way that these forms can connect to and retrieve data from database servers.[3] In this paper, we present an automatic annotation approach that first aligns the data units on a result page into different groups such that the data in the same group have the same semantic. And then we assign labels to each of this group

A study of ‘calf-path’ in file naming in institutional repositories in India
This study examined the file naming practices in 39 institutional repositories. There is evidence that calf-path exists infile naming among the curators of institutional repositories in India. The study showed that no standard or logic seems tohave been followed by repositories in the naming of the files, except by the National Digital Library of India (NDLI) and theCSIR-National Institute of Science Communication and Policy Research (CSIR-NIScPR). The study also examined thecomposition of the filenames, which shows that the author names (11.2%), titles (11.9%), journal title with volume and issuenumbers (21.1%) form the basis for the formation of filenames. It is suggested that digital repository managers have to givemore attention to name files in the institutional repository in the interest of uniformity and consistency
Procedures for the Seed Production of Pearl Millet Varieties
This is a guide to the techniques required to produce pure and vigorous seed from varieties of this cross-pollinated crop. Multiplication rates, through sequential breeder, foundation, and certified seed stages, are high:3 kg of seed are adequate for sowing 1 ha, subsequently producing 1 tonne of clean seed. Nucleus seed plots (stage 0), sown for regeneration once every 4 years, should be effectively is o- lated . They should be between 0,1 and 0.2 ha in size, and contain at least 3000 plants. Plots of breeder seed(stage1)should similarly be well isolated, and rigorously inspected and rogued, and not more than 1% of off - types should be permit tedatfinal inspection. Plot sizes are normally between 0.1 and 0.5 ha, according to how much certified seed is required, using a conservative multiplication factor of X200. At the end of the foundation seed stage (stage 2), through protective perimeter planting, inspection, and rogueing, off-types should be less than 2%. At the final certified seed stage(3), the permitted level of off-types is 5%. Six points of guidance are given for extension staff to pass on to farmers who(as may be expected) at tempt to multiply their own improved seed
